Reaktionsschritte

7-[4-(2-butoxyethoxy)phenyl]-1-(trifluoroacetyl)-2,3-dihydro-1-benzazepine-4-carboxylic acid (0.50 g) was dissolved in DMF (10 ml), 4-[(2-pyridinylsulfanyl)methyl]aniline (272 mg) and 1-hydroxybenzotriazole (321 mg) were added to the mixture, 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide chloride (401 mg) and triethylamine (0.44 ml) were added to the mixture, and the mixture was stirred for 16 hours at room temperature. The reaction solution was added to water, and extracted with ethyl acetate. The organic layer was washed with saturated brine, and dried over magnesium sulfate. The solvent was removed under reduced pressure, and the obtained residue was purified by silica gel column chromatography, to give 7-[4-(2-butoxyethoxy)phenyl]-N-[4-[(2-pyridinylsulfanyl)methyl]phenyl]-1-(trifluoroacetyl)-2,3-dihydro-1-benzazepine-4-carboxamide (Compound 199) (0.36 g).
